I am using -bios u-boot.bin and no luck, I get live signal. I am using latest u-boot master and qemu master. Command: $ ./qemu-system-ppc -M ppce500 -nographic -bios u-boot.bin Tried to load u-boot as well, same. Are there any patches pending or any tweak that should be done? Is there any way to provide more information? I tried: $ ./qemu-system-ppc -M ppce500 -nographic -M ppce500 -m 256 -s -S $ gdb (gdb) target remote :1234 Remote debugging using :1234 warning: Can not parse XML target description; XML support was disabled at compile time 0x00000000 in ?? () (gdb) load u-boot Loading section .bootpg, size 0x2f4 lma 0xf00000 Load failed How can I inject the firmware using gdb? Thanks!

Yes, that command should work with the right patches :). Unfortunately they are not in master yet, but instead waiting in my queue: https://github.com/agraf/qemu Please give things a try with the ppc-next branch in there. That should get things working for you. If you also want to run this using KVM, please keep in mind that you need a few extra patches that are in my kvm-ppc-queue branch as well.

It should make the payload's physical address available through an environment variable. If it's a uImage, it will get loaded automatically. For (3) you can use all the emulated block storage options QEMU provides, such as virtio-pci or ahci. > see solution but have either mtd or other block device support... is > that possible? It's definitely possible, yes :). I simply didn't implement any mtd device emulation so far in the QEMU machine model. But patches are definitely welcome!

Yes, the only device that I managed to get working was the emulated e1000 adapter. There are no virtio drivers in u-boot and the AHCI driver didn't compile for me :). > >>> see solution but have either mtd or other block device support... is >>> that possible? >> >> It's definitely possible, yes :).
